Answer:
They are the smallest pancise of any matere
Answer:
Car speedometer only measures speed and doesn't give any information about direction. So yes to speed, no to velocity.
Answer:
11.306 nm/s
or
113.06 atomic layers/sec
Explanation:
Hello!
First we need to know how much an inch equals in nanometers and a day in seconds:
Since <em>1inch = 2.54cm</em> and <em>1cm=10^7nm</em>
<em> </em>1 inch = 2.54 * 10^7 nm<em> </em>
<em />
Also <em>1day = 24hours = 24*60minutes = 24*60*60seconds</em>
<em> </em>1 day = 86.4 * 10^3 s
Therefore the rate at which the hair grows in nanometers per seconds is:
1/26 in/day = (1/26) * (2.54*10^7)/(86.4*10^3) = 11.306 nm/s
Now, if 1 atomic layer = 0.1 nm this means that 1 nm = 10 atomic layers.
Therefore:
The rate in atomic layers is
11.306 nm/s = 11.306 (10 atomic layers)/s = 113.06 atomic layers/sec

Accelerated motion = any change in speed or direction.
A. No. The airplane's speed is increasing.
B. No. The boulder's speed increases as it falls.
C. No. The speed of the ball decreases as it approaches the peak,
then it changes direction, begins to move downward, and its speed
increases steadily after that.
D. Yes. The cyclist's speed and direction are not changing.
